In the IoT world, MQTT (Message Queue Telemetry Transport protocol) and OPC-UA (OPC Unified Architecture) have established themselves as open and platform-independent standards for data exchange in Industrial Internet of Things (IIoT) and Industry 4.0 use cases. Data streaming with Apache Kafka is the data hub for integrating and processing massive volumes of data at any scale in real-time. This article explores the relationship between Kafka and the IoT protocols, when to use which technology, and why sometimes HTTP/REST is the better choice. The conclusion explores real-world case studies from Audi and BMW.
